Read header row in datatable into combobox

Question

Hi all,

Hoping someone might be able to point me in the right direction.

I have a winforms application that imports data from a csv file into a datatable. I now need to read the header row from the datatable & use that as a list in a combobox. Any ideas as I'm stuck on howto do this.

Many thanks

Charlie

if you want to restrict user from saving when txtcontent is null then you can use validation control, else write your query in if (txtContent.text !="").
